Description
The polarized excitation and emission spectra of the U6+ molecular centers giving the most intense emission lines at 18 940 cm-1 and 19 285 cm-1 are presented and analyzed in detail. From the polarization experiments, it is shown that the symmetry of the centers is C4sub(v) and that the symmetries of the observed electronic states are GAMMA2, GAMMA1 and GAMMA5. Finally, an electronic model is proposed which associates the emission and excitation lines of the U6+ centers in the visible region to transitions between the fundamental state GAMMA1 (6p6,1S) and the states of the excited configuration 6p5 (2Psub(3/2)) 7s.
